STENCIL-MACHINE FOR PRINTING WRAPPERS.

SPECIFICATION forming part of Letters Patent No. 581,259, dated April 27, 1897.

Application filed November 7, 1896. Serial No. 611,349%. (No model.)

To all whom it may concern:

Be it known that I, EDWIN D. BELKNAP, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Stencil-Machines for Printing WVrappers; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the art of printing; and it consists of an improved machine for printingwrappers for newspapers, pamphlets, &c., by means of stencil-cards.

My invention is more especially designed as an attachment to the stencil-printing machine described in an application for patent filed by Frank D. Belknap of even date herewith. I

In the accompanying sheet of drawings, Figure 1 is a side elevation and partial section of my machine. Fig. 2 is an enlarged detail View of the cutting-rollers.

Throughout the drawings like referencefigures refer to like parts.

1 is the main frame, 2 the driving-shaft, and 3 the driving-pulley.

4 is a sprocket from which motion is transmitted to the machine by gearing. (Not shown.)

15 is an ink-carrying roller on the shaft 10, having its face more or less cutaway.

14 is a coacting roller, also having parts of its face cut away. The full-faced portions left on these rollers correspond and travel at the same circumferential speed. The inkingroll17 revolves in the ink-fount 18, having the doctor-block 19, adjustable by screw 20. This roll runs at the same speed as roller 15 and comes in contact with the full-faced portion thereof.

A series of stencilcards are fed between the rollers 14 and 15. .This may be done by hand, but I prefer to have them fed along the guides 30 from the pile 21 in the magazine 22 by some form of automatic mechanism.

36 is a collection-box for these cards after they have been discharged from the printing mechanism. The box 36 slides on the rod 51.

is a standard attached to the main frame of the machine, preferably over the roller 14.

A web of paper 57 is mounted on a shaft 56, rotating in said standard 55. This web passes around the guide-roller 58 and through the printing mechanism.

59 represents a sprocket-chain driven from the shaft of the inking-roll 17 and running over a sprocket-wheel 60 on the shaft 61.

62 is a roller mounted on said shaft 61, having a slot formed therein, and indicated at 63, Fig. 2.

64 is a parallel shaft which rotates in unison with 61 by reason of the intermeshing gears 65 and 66.

67 is a knife mounted in roller 64 on shaft 64, backed by a strip of india-rubber 68, and meshing with the slot 63. These shafts (31 and 61 are journaled in housing 70, adjustably mounted on the shaft 69.

71 is a table for receiving the printed and cut wrappers.

Corresponding portions of the rollers 62 and 64 are cut away, as indicated at 72 72.

The operation of my invention is as follows: Motion is given to the rollers 141 and 15 and the stencil-cards are fed forward to the point of tangency thereof. They and the web of paper together are seized periodically by the full-faced portions of the rollers and by them are fed forward a slight amount. During such action the ink on roller 15 is forced through the stencil-card and prints the address on the web. The card which has been used is forced into the collection-box by the next succeeding card or by any special form of ejector mechanism that may be employed. The web 57 is fed forward by the rollers 62 and 64., except during the time when the rollers 14 and 15 seize it between the full portions of their faces. and 15 are acting in that manner, the web is left free to follow the motions thereby imparted by reason of the fact that it is released from the grasp of the rollers 62 and 64 because of the cut-away portions '72 therein. The knife 67 cuts said web into sections equal to the length of the wrapper in the well known way; Motion is given to the wrapper cutting and feeding mechanism by the sprocket-chain 59. Difierent sets of cutting and feeding rollers have to be substituted for the production of wrappers of dif ferent lengths.

While these rollers 14 ICO Numerous changes could be made in the details of my invention without departing from the principle thereof; The number of full-faced portions of the rollers 1% and 15 might be varied if their relative speeds of rotation were varied accordingly. Other forms of stencil-feeding card mechanism and different forms of stencil-cards might be used, and so on, without detracting from the advantages of my improved apparatus, which consist in its compactness and smoothness and rapidity of action combined with small first cost.

It is evident that in order to prevent the smearing of ink on the paper to be printed the dimension of the ink-carrying pad or roller 15 in the line of its motion should be only equal to and preferably less than the width of the stencil-card. In the particular construction which I have here illustrated it is also necessary that the other dimension of the ink-carrying pad in the line of its axis should be less than the distance between the parallel guides in order that it may pass between th em and grip the stencil-card. Consequently the dimensions of the ink-carryin g pad both ways should be less than the dimensions of the stencilcard.

Having therefore described my invention, what I claim as new, and desire to protect by Letters Patent, is-

1. In a machine for printing wrappers, the combination of the two coacting, partly-cutaway rollers, one of which carries ink, means for guiding stencil-cards and a web of paper to be printed to said rollers, and a pair of rollers one of which carries a knife, located in the line of travel of the printed web delivered from said first-mentioned rollers, substantially as described.

2. I11 a machine for printing wrappers, the combination of the two coacting, partly-cutaway rollers, one of which carries ink, means for guiding stencil-cards and a web of paper to be printed, to said rollers, and a second pair of rollers one of which carries a knife, located in the line of travel of the printed web, said last-mentioned rollers being also cut away at points which correspond to the full-faced portion of the ink-carrying roller, substantially as described.

In a stencil-wrapper-pl'inting machine, the combination of the two coacting rollers, one of which carries ink, the shaft arranged to carry a roll of paper journaled in the main frame, and the guides which deliver a series of stencil-cards to the point of tangency of the rollers, substantially as described.

4;. In a stencilwrapper-printing machine, the combination of the two coacting rollers, one of which carries ink, the shaft arranged to carry a roll of paper j ournaled in the main frame, and the guides which deliver a series of stencil-cards to the point of tangency of the rollers, together with a knife located in the path of the printed web of paper, substantially as described.

5. In a machine for printing wrappers, the combination of the two coacting rollers, one or both of which has its face cut away in part, and one of which carries ink, the shaft arranged to carry a roll of paper journaled in the main frame, the guides which deliver a series of stencil-cards to the point of tangency of the rollers, and a second pair of rollers, one of which carries a knife, located in the line of travel of the printed web of paper, one or both of said last-mentioned rollers being also cut away at points which correspond to the f ull-faced portions of the other set of rollers, substantiallyas described.

In testimony whereof I aiiix my signature in presence of two witnesses.
